-\section{Thread functions}\label{threadfunctions}
+\section{Application initialization and termination}\label{appinifunctions}
-\wxheading{Include files}
+The functions in this section are used on application startup/shutdown and also
+to control the behaviour of the main event loop of the GUI programs.
-<wx/thread.h>
+\membersection{::wxEntry}\label{wxentry}
-\wxheading{See also}
+This initializes wxWindows in a platform-dependent way. Use this if you
+are not using the default wxWindows entry code (e.g. main or WinMain). For example,
+you can initialize wxWindows from an Microsoft Foundation Classes application using
+this function.
-\helpref{wxThread}{wxthread}, \helpref{wxMutex}{wxmutex}, \helpref{Multithreading overview}{wxthreadoverview}
+\func{void}{wxEntry}{\param{HANDLE}{ hInstance}, \param{HANDLE}{ hPrevInstance},
+ \param{const wxString\& }{commandLine}, \param{int}{ cmdShow}, \param{bool}{ enterLoop = TRUE}}
-\membersection{::wxMutexGuiEnter}\label{wxmutexguienter}
+wxWindows initialization under Windows (non-DLL). If {\it enterLoop} is FALSE, the
+function will return immediately after calling wxApp::OnInit. Otherwise, the wxWindows
+message loop will be entered.
-\func{void}{wxMutexGuiEnter}{\void}
+\func{void}{wxEntry}{\param{HANDLE}{ hInstance}, \param{HANDLE}{ hPrevInstance},
+ \param{WORD}{ wDataSegment}, \param{WORD}{ wHeapSize}, \param{const wxString\& }{ commandLine}}
-This function must be called when any thread other than the main GUI thread
-wants to get access to the GUI library. This function will block the execution
-of the calling thread until the main thread (or any other thread holding the
-main GUI lock) leaves the GUI library and no other thread will enter the GUI
-library until the calling thread calls \helpref{::wxMutexGuiLeave()}{wxmutexguileave}.
+wxWindows initialization under Windows (for applications constructed as a DLL).
-Typically, these functions are used like this:
+\func{int}{wxEntry}{\param{int}{ argc}, \param{const wxString\& *}{argv}}
-\begin{verbatim}
-void MyThread::Foo(void)
-{
- // before doing any GUI calls we must ensure that this thread is the only
- // one doing it!
+wxWindows initialization under Unix.
- wxMutexGuiEnter();
+\wxheading{Remarks}
- // Call GUI here:
- my_window->DrawSomething();
+To clean up wxWindows, call wxApp::OnExit followed by the static function
+wxApp::CleanUp. For example, if exiting from an MFC application that also uses wxWindows:
- wxMutexGuiLeave();
+\begin{verbatim}
+int CTheApp::ExitInstance()
+{
+ // OnExit isn't called by CleanUp so must be called explicitly.
+ wxTheApp->OnExit();
+ wxApp::CleanUp();
+
+ return CWinApp::ExitInstance();
}
\end{verbatim}
-Note that under GTK, no creation of top-level windows is allowed in any
-thread but the main one.
-
-This function is only defined on platforms which support preemptive
-threads.

-\membersection{::wxMutexGuiLeave}\label{wxmutexguileave}
-
-\func{void}{wxMutexGuiLeave}{\void}
-
-See \helpref{::wxMutexGuiEnter()}{wxmutexguienter}.

-\membersection{::wxDirExists}
+<wx/app.h>
-\func{bool}{wxDirExists}{\param{const wxString\& }{dirname}}
+\membersection{::wxHandleFatalExceptions}\label{wxhandlefatalexceptions}
-Returns TRUE if the directory exists.
+\func{bool}{wxHandleFatalExceptions}{\param{bool}{ doIt = TRUE}}
-\membersection{::wxDos2UnixFilename}
+If {\it doIt} is TRUE, the fatal exceptions (also known as general protection
+faults under Windows or segmentation violations in the Unix world) will be
+caught and passed to \helpref{wxApp::OnFatalException}{wxapponfatalexception}.
+By default, i.e. before this function is called, they will be handled in the
+normal way which usually just means that the application will be terminated.
+Calling wxHandleFatalExceptions() with {\it doIt} equal to FALSE will restore
+this default behaviour.
-\func{void}{wxDos2UnixFilename}{\param{wxChar *}{s}}
+\membersection{::wxInitAllImageHandlers}\label{wxinitallimagehandlers}
-Converts a DOS to a Unix filename by replacing backslashes with forward
-slashes.
+\func{void}{wxInitAllImageHandlers}{\void}
-\membersection{::wxFileExists}
+Initializes all available image handlers. For a list of available handlers,
+see \helpref{wxImage}{wximage}.
-\func{bool}{wxFileExists}{\param{const wxString\& }{filename}}
+\wxheading{See also}
-Returns TRUE if the file exists. It also returns TRUE if the file is
-a directory.
+\helpref{wxImage}{wximage}, \helpref{wxImageHandler}{wximagehandler}
-\membersection{::wxFileModificationTime}\label{wxfilemodificationtime}
+\wxheading{Include files}
-\func{time\_t}{wxFileModificationTime}{\param{const wxString\& }{filename}}
+<wx/image.h>
-Returns time of last modification of given file.
+\membersection{::wxInitialize}\label{wxinitialize}
-\membersection{::wxFileNameFromPath}
+\func{bool}{wxInitialize}{\void}
-\func{wxString}{wxFileNameFromPath}{\param{const wxString\& }{path}}
+This function is used in wxBase only and only if you don't create
+\helpref{wxApp}{wxapp} object at all. In this case you must call it from your
+{\tt main()} function before calling any other wxWindows functions.
-\func{char*}{wxFileNameFromPath}{\param{char* }{path}}
+If the function returns {\tt FALSE} the initialization could not be performed,
+in this case the library cannot be used and
+\helpref{wxUninitialize}{wxuninitialize} shouldn't be called neither.
-Returns the filename for a full path. The second form returns a pointer to
-temporary storage that should not be deallocated.
+This function may be called several times but
+\helpref{wxUninitialize}{wxuninitialize} must be called for each successful
+call to this function.
-\membersection{::wxFindFirstFile}\label{wxfindfirstfile}
+\wxheading{Include files}
-\func{wxString}{wxFindFirstFile}{\param{const char*}{spec}, \param{int}{ flags = 0}}
+<wx/app.h>
-This function does directory searching; returns the first file
-that matches the path {\it spec}, or the empty string. Use \helpref{wxFindNextFile}{wxfindnextfile} to
-get the next matching file. Neither will report the current directory "." or the
-parent directory "..".
+\membersection{::wxSafeYield}\label{wxsafeyield}
-{\it spec} may contain wildcards.
+\func{bool}{wxSafeYield}{\param{wxWindow*}{ win = NULL}}
-{\it flags} may be wxDIR for restricting the query to directories, wxFILE for files or zero for either.
+This function is similar to wxYield, except that it disables the user input to
+all program windows before calling wxYield and re-enables it again
+afterwards. If {\it win} is not NULL, this window will remain enabled,
+allowing the implementation of some limited user interaction.
-For example:
+Returns the result of the call to \helpref{::wxYield}{wxyield}.
-\begin{verbatim}
- wxString f = wxFindFirstFile("/home/project/*.*");
- while ( !f.IsEmpty() )
- {
- ...
- f = wxFindNextFile();
- }
-\end{verbatim}
+\wxheading{Include files}
-\membersection{::wxFindNextFile}\label{wxfindnextfile}
+<wx/utils.h>
-\func{wxString}{wxFindNextFile}{\void}
+\membersection{::wxUninitialize}\label{wxuninitialize}
-Returns the next file that matches the path passed to \helpref{wxFindFirstFile}{wxfindfirstfile}.
+\func{void}{wxUninitialize}{\void}
-See \helpref{wxFindFirstFile}{wxfindfirstfile} for an example.
+This function is for use in console (wxBase) programs only. It must be called
+once for each previous successful call to \helpref{wxInitialize}{wxinitialize}.
-\membersection{::wxGetDiskSpace}\label{wxgetdiskspace}
+\wxheading{Include files}
-\func{bool}{wxGetDiskSpace}{\param{const wxString\& }{path}, \param{wxLongLong }{*total = NULL}, \param{wxLongLong }{*free = NULL}}
+<wx/app.h>
-This function returns the total number of bytes and number of free bytes on
-the disk containing the directory {\it path} (it should exist). Both
-{\it total} and {\it free} parameters may be {\tt NULL} if the corresponding
-information is not needed.
+\membersection{::wxYield}\label{wxyield}
-\wxheading{Returns}
+\func{bool}{wxYield}{\void}
-{\tt TRUE} on success, {\tt FALSE} if an error occured (for example, the
-directory doesn't exist).
+Calls \helpref{wxApp::Yield}{wxappyield}.
-\wxheading{Portability}
+This function is kept only for backwards compatibility, please use
+\helpref{wxApp::Yield}{wxappyield}method instead in any new code.
-This function is implemented for Win16 (only for drives less than 2Gb), Win32,
-Mac OS and generic Unix provided the system has {\tt statfs()} function.
+\wxheading{Include files}
-This function first appeared in wxWindows 2.3.2.
+<wx/app.h> or <wx/utils.h>
-\membersection{::wxGetOSDirectory}\label{wxgetosdirectory}
+\membersection{::wxWakeUpIdle}\label{wxwakeupidle}
-\func{wxString}{wxGetOSDirectory}{\void}
+\func{void}{wxWakeUpIdle}{\void}
-Returns the Windows directory under Windows; on other platforms returns the empty string.
+This functions wakes up the (internal and platform dependent) idle system, i.e. it
+will force the system to send an idle event even if the system currently {\it is}
+ idle and thus would not send any idle event until after some other event would get
+sent. This is also useful for sending events between two threads and is used by
+the corresponding functions \helpref{::wxPostEvent}{wxpostevent} and
+\helpref{wxEvtHandler::AddPendingEvent}{wxevthandleraddpendingevent}.
-\membersection{::wxIsAbsolutePath}
+\wxheading{Include files}
-\func{bool}{wxIsAbsolutePath}{\param{const wxString\& }{filename}}
+<wx/app.h>
-Returns TRUE if the argument is an absolute filename, i.e. with a slash
-or drive name at the beginning.
+\section{Process control functions}\label{processfunctions}
-\membersection{::wxPathOnly}
+The functions in this section are used to launch or terminate the other
+processes.
-\func{wxString}{wxPathOnly}{\param{const wxString\& }{path}}
+\membersection{::wxExecute}\label{wxexecute}
-Returns the directory part of the filename.
+\func{long}{wxExecute}{\param{const wxString\& }{command}, \param{int }{sync = wxEXEC\_ASYNC}, \param{wxProcess *}{callback = NULL}}
-\membersection{::wxUnix2DosFilename}
+\func{long}{wxExecute}{\param{char **}{argv}, \param{int }{flags = wxEXEC\_ASYNC}, \param{wxProcess *}{callback = NULL}}
-\func{void}{wxUnix2DosFilename}{\param{const wxString\& }{s}}
+\func{long}{wxExecute}{\param{const wxString\& }{command}, \param{wxArrayString\& }{output}}
-Converts a Unix to a DOS filename by replacing forward
-slashes with backslashes.
+\perlnote{In wxPerl this function only takes the {\tt command} argument,
+and returns a 2-element list {\tt ( status, output )}, where {\tt output} is
+an array reference.}
-\membersection{::wxConcatFiles}
+\func{long}{wxExecute}{\param{const wxString\& }{command}, \param{wxArrayString\& }{output}, \param{wxArrayString\& }{errors}}
-\func{bool}{wxConcatFiles}{\param{const wxString\& }{file1}, \param{const wxString\& }{file2},
-\param{const wxString\& }{file3}}
+\perlnote{In wxPerl this function only takes the {\tt command} argument,
+and returns a 3-element list {\tt ( status, output, errors )}, where
+{\tt output} and {\tt errors} are array references.}
-Concatenates {\it file1} and {\it file2} to {\it file3}, returning
-TRUE if successful.
+Executes another program in Unix or Windows.
-\membersection{::wxCopyFile}
+The first form takes a command string, such as {\tt "emacs file.txt"}.
-\func{bool}{wxCopyFile}{\param{const wxString\& }{file1}, \param{const wxString\& }{file2}, \param{bool }{overwrite = TRUE}}
+The second form takes an array of values: a command, any number of
+arguments, terminated by NULL.
-Copies {\it file1} to {\it file2}, returning TRUE if successful. If
-{\it overwrite} parameter is TRUE (default), the destination file is overwritten
-if it exists, but if {\it overwrite} is FALSE, the functions failes in this
-case.
+The semantics of the third and fourth versions is different from the first two
+and is described in more details below.
-\membersection{::wxGetCwd}\label{wxgetcwd}
+If {\it flags} parameter contains {\tt wxEXEC\_ASYNC} flag (the default), flow
+of control immediately returns. If it contains {\tt wxEXEC\_SYNC}, the current
+application waits until the other program has terminated.
-\func{wxString}{wxGetCwd}{\void}
+In the case of synchronous execution, the return value is the exit code of
+the process (which terminates by the moment the function returns) and will be
+$-1$ if the process couldn't be started and typically 0 if the process
+terminated successfully. Also, while waiting for the process to
+terminate, wxExecute will call \helpref{wxYield}{wxyield}. The caller
+should ensure that this can cause no recursion, in the simplest case by
+calling \helpref{wxEnableTopLevelWindows(FALSE)}{wxenabletoplevelwindows}.
-Returns a string containing the current (or working) directory.
+For asynchronous execution, however, the return value is the process id and
+zero value indicates that the command could not be executed. As an added
+complication, the return value of $-1$ in this case indicattes that we didn't
+launch a new process, but connected to the running one (this can only happen in
+case of using DDE under Windows for command execution). In particular, in this,
+and only this, case the calling code will not get the notification about
+process termination.
-\membersection{::wxGetWorkingDirectory}
+If callback isn't NULL and if execution is asynchronous,
+\helpref{wxProcess::OnTerminate}{wxprocessonterminate} will be called when
+the process finishes. Specifying this parameter also allows you to redirect the
+standard input and/or output of the process being launched by calling
+\helpref{Redirect}{wxprocessredirect}. If the child process IO is redirected,
+under Windows the process window is not shown by default (this avoids having to
+flush an unnecessary console for the processes which don't create any windows
+anyhow) but a {\tt wxEXEC\_NOHIDE} flag can be used to prevent this from
+happening, i.e. with this flag the child process window will be shown normally.
+
+Under Unix the flag {\tt wxEXEC\_MAKE\_GROUP\_LEADER} may be used to ensure
+that the new process is a group leader (this will create a new session if
+needed). Calling \helpref{wxKill}{wxkill} with the argument of -pid where pid
+is the process ID of the new process will kill this process as well as all of
+its children (except those which have started their own session).
-\func{wxString}{wxGetWorkingDirectory}{\param{char*}{buf=NULL}, \param{int }{sz=1000}}
+Finally, you may use the third overloaded version of this function to execute
+a process (always synchronously) and capture its output in the array
+{\it output}. The fourth version adds the possibility to additionally capture
+the messages from standard error output in the {\it errors} array.
-This function is obsolete: use \helpref{wxGetCwd}{wxgetcwd} instead.
+See also \helpref{wxShell}{wxshell}, \helpref{wxProcess}{wxprocess},
+\helpref{Exec sample}{sampleexec}.
-Copies the current working directory into the buffer if supplied, or
-copies the working directory into new storage (which you must delete yourself)
-if the buffer is NULL.
+\wxheading{Parameters}
-{\it sz} is the size of the buffer if supplied.
+\docparam{command}{The command to execute and any parameters to pass to it as a
+single string.}
-\membersection{::wxGetTempFileName}
+\docparam{argv}{The command to execute should be the first element of this

-launch a new process, but connected to the running one (this can only happen in
-case of using DDE under Windows for command execution). In particular, in this,
-and only this, case the calling code will not get the notification about
-process termination.
+This macro creates either a cursor (MSW) or an icon (elsewhere) with the given

+loaded from XPM file under other platforms.
-If callback isn't NULL and if execution is asynchronous (note that callback

+the wxASSERT and wxFAIL macros only do anything if \_\_WXDEBUG\_\_ is defined
+(in other words, in the debug build) but disappear completely in the release
+build. On the other hand, the wxCHECK macros stay event in release builds but a
